Inductor element, coil antenna, antenna device, card information medium, and electronic device

An inductor element comprising:

• an insulator that includes a first principal surface and a second principal surface opposing to the first principal surface;
• a coil conductor that is provided on or in the insulator, that has a winding axis, and that includes a first end and a second end;
• a first pad electrode that is provided at the first principal surface, and that is electrically connected to the first end side;
• a second pad electrode that is provided at the first principal surface, and that is electrically connected to the second end side;
• a third pad electrode that is provided at the second principal surface, and that is electrically connected to a position different from a connected position of the first pad electrode on the second end side;
• and
• a fourth pad electrode that is provided at the second principal surface, and that is electrically connected to a position different from a connected position of the second pad electrode on the second end side;
• wherein
• the first pad electrode, the second pad electrode, the third pad electrode, and the fourth pad electrode are independent of one another;
• and
• an inductance component between the first pad electrode and the second pad electrode is different from an inductance component between the second pad electrode and the third pad electrode.
